Description

Technical Field

[0001] The utility model relates to the technical field of vacuum cleaners, in particular to a comb tooth mechanism of a roller brush cover. Background Art

[0002] With the development of technology, sweeping robots can greatly save manpower in cleaning household floors and are widely used.

[0003] When the sweeping robot is cleaning the floor, the roller brush installed inside the brush cover rotates to roll up the garbage on the floor. The smooth inner wall of the brush cover guides the debris to the suction port. The vacuum cleaner inside the sweeping robot then absorbs the garbage in the suction port and sucks it into the storage box for storage. However, when the roller brush is cleaning hair, the hair will be entangled on the outer wall of the roller brush. As the roller brush continues to operate, the hair will be entangled more and more tightly on the outer wall of the roller brush, making it difficult to remove and clean the entangled hair when the roller brush is cleaning. Utility Model Content

[0004] The main purpose of the utility model is to provide a comb tooth mechanism of a roller brush cover, aiming to solve the problem in the prior art that when the roller brush rotates, the hair becomes increasingly entangled on the outer wall of the roller brush.

[0005] In order to achieve the above-mentioned purpose of the utility model, the first aspect of the utility model proposes a roller brush cover comb mechanism, comprising:

[0006] Cover body;

[0007] The comb tooth assembly includes a comb tooth block, the bottom of the comb tooth block is provided with a plurality of hook angles for lifting hair, the bottom of the comb tooth assembly is provided with a plurality of hook grooves for hooking hair, and the hook grooves are located at the top of the hook angles, wherein the comb tooth block is installed on the cover body.

[0008] Furthermore, a plurality of arcuate edges are provided at the bottom of the comb tooth block, and the top end of the comb tooth block is fixedly connected to the top end of the inner wall of the cover body.

[0009] Furthermore, the comb tooth block is arranged obliquely toward the center line of the cover body.

[0010] Furthermore, a cleaning component for cleaning garbage is provided inside the cover.

[0011] Furthermore, the cleaning assembly includes a roller brush cylinder, and the outer wall of the roller brush cylinder is fixedly connected with a rubber strip and roller brush bristles.

[0012] Beneficial effects:

[0013] The comb tooth mechanism of the roller brush cover of the present invention drives the entangled hair to rotate toward the comb tooth block when the roller brush barrel rotates. At this time, the hair will be hooked by the hook corner and enter the inside of the hook groove, thereby achieving the effect of combing and picking up the entangled hair, preventing the hair from becoming more and more entangled on the outer wall of the roller brush barrel, so as to facilitate the cleaning of the hair on the outer wall of the roller brush barrel in the later stage.

[0024] Reference Figure 1-3 The roller brush cover comb mechanism of an embodiment of the present invention includes:

[0025] Cover 2;

[0026] The comb tooth assembly 1 includes a comb tooth block 11, and the bottom of the comb tooth block 11 is provided with multiple hook corners 12 for picking up hair. The bottom of the comb tooth assembly 1 is provided with multiple hook grooves 13 for hooking hair, and the hook grooves 13 are located at the top of the hook corners 12, wherein the comb tooth block 11 is installed on the cover body 2.

[0027] Specifically, a plurality of arcuate edges 14 are formed at the bottom of the comb block 11 , the top of the comb block 11 is fixedly connected to the top of the inner wall of the cover 2 , and the comb block 11 is tilted toward the center line of the cover 2 .

[0028] Furthermore, the comb tooth assembly 1 is provided with multiple groups, the number of groups is an even number, and the multiple groups are divided into two parts, which are symmetrically arranged on both sides of the bottom end of the cover body 2. The comb tooth assemblies 1 of the two parts are all obliquely arranged and distributed in an eight-shaped shape, facing the direction of rotation of the roller brush cylinder 3. The hair wrapped around the outer wall of the roller brush cylinder 3 will be hooked by the hook corner 12, and then the hooked part of the hair will penetrate into the hook groove 13. As the roller brush cylinder 3 continues to rotate, it will pull the hair to achieve the combing effect of the hair, thereby avoiding the situation where the hair and the roller brush cylinder 3 become more and more entangled as the roller brush cylinder 3 rotates.

[0029] Specifically, the interior of the cover body 2 is provided with a cleaning component for cleaning garbage, and the cleaning component includes a roller brush cylinder 3, the outer wall of which is fixedly connected with a rubber strip 4 and a roller brush bristle 5, the rubber strip 4 is used to extend into the blanket for cleaning, and the roller brush bristle 5 is used to lift debris on the ground.

[0030] Furthermore, the cover body 2 is a roller brush mounting cover at the bottom of the existing sweeping robot. The cover body 2 is fixedly mounted to the body at the bottom of the sweeping robot by bolts. Circular grooves for plugging in the two ends of the roller brush barrel 3 are respectively provided on both sides of the cover body 2, so as to receive the two ends of the roller brush barrel 3 and prevent the roller brush barrel 3 from falling or shaking when the roller brush barrel 3 is rotating. The cover body 2 is a mounting cover for the roller brush barrel 3 of the existing sweeping robot. The rubber strip 4 and the roller brush bristles 5 are two main cleaning components of the sweeping robot. The rubber strip 4 is generally made of durable plastic or rubber so that it can be in contact with the ground It maintains elasticity during friction, and the roller brush bristles 5 are usually made of synthetic fibers or nylon. The rubber strip 4 is V-shaped and is provided in multiple groups. They are evenly spaced and annularly distributed on the outer wall of the roller brush cylinder 3 and fixedly connected to the outer wall of the roller brush cylinder 3 by bolts. There are multiple roller brush bristles 5, and the arrangement corresponds to the shape of the rubber strip 4. Therefore, when the roller brush cylinder 3 rolls, the rubber strip 4 and the roller brush bristles 5 are driven to clean the ground at the same time. The rubber strip 4 and the roller brush bristles 5 lift the garbage on the ground and rotate and transport them in the direction close to the comb tooth assembly 1, so that the hair wrapped around the outer wall of the roller brush cylinder 3 needs to be combed by the comb tooth assembly 1.

[0031] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
